Relationship between mild cognitive decline and oral motor functions in metropolitan community-dwelling older Japanese: The Takashimadaira study

Olfactory impairment in older adults is associated with cognitive decline. This study describes the development of a Brief Odor Detection Test (B-ODT), and its pilot administration in community-dwelling older adults. The study aimed at examining whether the test could differentiate older adults with very mild cognitive impairment from their cognitively healthy counterparts. The sample consisted of 34 older adults (22 women), aged from 65 to 87 years. Participants were divided into two groups according to their general cognitive functioning. Odor detection was measured via vanillin solutions at the following concentrations: 150 mg/L, 30 mg/L, 15 mg/L, 3 mg/L, and .03 mg/L. The first condition of the test involved a scale administration of vanillin solutions. The second condition examined the change in air odour and it required vanillin solution of 30 mg/L and a metric ruler of 30 cm. The examiner had to place the solution at a specific distance point from each nostril. Odour identification sensitivity was secondarily measured. The results showed statistically significant differences in odour detection threshold between the two groups. In the unirhinal testing, left nostril differences of the two groups were definite. Hence, the B-ODT seems a promising instrument for very early cognitive impairment screening in older adult population.

Increased Risk

Abstract Hearing impairment in older adults is linked to accelerated cognitive decline and a 94% increased risk of incident dementia in population-based observational studies. Whether hearing treatment can delay cognitive decline is unknown but could have substantial clinical and public health impact. The NIH-funded ACHIEVE randomized controlled trial of 977 older adults aged 70-84 years with untreated mild-to-moderate hearing loss, is testing the efficacy of hearing treatment versus health education on cognitive decline over 3 years in community-dwelling older adults (Clinicaltrials.gov Identifier: NCT03243422.) This presentation will describe lessons learned from ACHIEVE’s unique study design. ACHIEVE is nested within a large, well-characterized multicenter observational study, the Atherosclerosis Risk in Communities Study. Such nesting within an observational study maximizes both operational and scientific efficiency. With trial results expected in 2022, this presentation will focus on the benefits gained in design and recruitment/retention, including dedicated study staff, well-established protocols, and established study staff-participant relationships.

Increased Risk

Abstract Home-based cognitive assessment (HBCA) services are emerging as a convenient alternative to in-clinic cognitive assessment and may aid in mitigating barriers to detecting cognitive impairment (CI). It is unknown which older adults would be likely to participate in HBCA. Here we investigated the role of age and Subjective Cognitive Decline (SCD). SCD has demonstrated an increased risk for progression to CI/dementia. A nation-wide community-dwelling sample of 494 adults age 50+ were recruited via Amazon Mechanical Turk to complete an online survey assessing perceptions around HBCA and SCD. Our sample was 91.9% White and 66.8% female. It consisted of 174 respondents aged 50-60, 265 aged 61- 70, and 55 aged 71-79. Age groups were comparable with respect to their acceptance of cognitive assessment (Range 4-20, higher score=higher acceptance, 7.9±3.3, 8.15±3.2, 8.05±3.43) and SCD-Q total (43.1±5.8, 43.2±5.7, 43.3±5.7). Correlation analysis revealed a relationship between SCD-QSCD total and perceived likelihood of participation in HBCA for those ages 61-70 (r(263) = .222 p = .000), but not for ages 50-60 or 71-79 (r(172) = .102 p = .152; r(53) = -.102 p = .458). Our findings suggest that SCD influences the likelihood of participation in HBCA for older adults’ transitioning to old age (61-70). Findings show that for adults transitioning into old age (61-70), perceived cognitive state influences their likelihood of participation in HBCA. Importantly, concerns about CI/dementia may generate more favorable perceptions of HBCA for this group.

The Individual

Introduction: The ability to use everyday technology (ET) is becoming increasingly necessary for maintaining domestic and social lives. For older adults, difficulties with using ETs can begin at the mild cognitive impairment (MCI) state and may indicate increasing cognitive decline. The aim of this study was to conduct a detailed investigation into the ability to use ETs among Japanese older community-dwelling adults at 3 stages of cognitive function and the ability to carry out daily activities. Method: We analyzed family members’ responses to questions about older adults with cognitive decline in their families. A total of 168 older adults with subjective memory complaints (SMC) or cognitive decline and inconvenience in daily life were analyzed. A questionnaire was used to assess the characteristics, ability to use ETs, and ability to manage refrigerator contents, all of which can be early signs of dementia. Participants were divided 3 groups by the type of dementia: SMC (n = 77), MCI (n = 36), and Alzheimer’s disease (AD) (n = 55) for comparison. Result: The observation list of early signs of dementia (OLD) total score indicated a significant positive correlation with the number of ET errors (r = 0.37, p < 0.001) and number of difficulties with refrigerator management (r = 0.18, p = 0.031). Regarding number of ET errors, there was a significant main effect for the 3 groups, and the SMC group made significantly fewer errors than the AD group (p = 0.02). In 7 of the 11 ET categories, errors with using ETs were associated with all 3 groups, with the SMC group making fewer errors, and the AD group making more. Regarding difficulties with refrigerator management, 2 out of 9 problems were associated with the 3 groups, with the SMC group having fewer difficulties and the AD group having more. Discussion/Conclusion: The results indicated that the ability to use ETs and to manage refrigerator contents begins to decline at the SMC stage. Further evaluation of the ability to use ETs is needed for older adults with SMC so that adequate support in the context of the individual can be provided.
